Hi,
Yes, I'm a newbie :) but it's a short question:
How can I check if an string contains alpha-numeric characters only?
I'm trying to check if a login name (given by the user) is valid or not.
I'm using something like:
#REFindNoCase('[[:alpha]]*|[[:digit]]*',attributes.usuario)# but it doesn't
work.
BTW, some links of POSIX regular expression are welcome.
thanks in advance
